To til whom it may concern:

Be it known that we, MILTON R. WARNER, a citizen of thel United States,residing at Manchester, and CHARLES O. BULOCK, a citizen of the UnitedStates, and ALEXANDER E. MCLAUCHLIN, a citizen of Canada, residing atYork Haven, in the county of York, State of Pennsylvania, have inventedcertain new and useful Improvements in Apparatus for Suspending,Raising, and Lowering Electric Lamps; and we do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe saine, reference being had-to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

Our invention relates to an apparatus for suspending, raising, andlowering electric lamps. Y

It has for its object to provide a construction which will be simple,efficient, and coniparatively inexpensive,and which will adinit of thelamp being suspended over a drive or road way, and which can be readilyand easily brought from over the roadway to a point at one side thereofand near the pavement, so that fresh carbons can be put in place withoutinterfering at all with trahie on the roadway or street.

To the accomplishment of the foregoing and such other objects as mayhereinafter appear the invention consists in the construction and in thecombination of parts.

hereinafter particularly described, and then sought to be speciiicallydefined bythe claims, reference being had to the accompanying drawings,forming a part hereof, and in which- Figure l is a side elevationshowing application of the invention. Fig. 2 is a detail side view ofthe lmnp-carriage. Fig. 3 is an end view of the saine and one of thetrackbraekets. Fig. a is an enlarged end view of one of thetrackbrackets. Figs. 5 and 6 are side and top views, respectively, ofthe connectingqglate for joining the track-sections. Fig. 7 is a detailof the supporting-sheave located at the curve in the track. Fig. S is adetail ci the sheave located upon the bracket Iingdrum.

at the outer end of the track. Fig. 9 is a cross-section through theboxing of the wind- Fig. l0 is a vertical section through one end ofsaid boxing, and Fig. l1 is an enlarged detail of a modified forni ofbracket.

In the drawings the numeral l designates two poles, one upon each sideoi' the roadway or street, and from one to the other of which extends acable 2, which will constitute a support for a track upon which alamp-carriage will travel, as hereinafter described.

The numeral 3 designates a track which is formed of sections of plates4, placed end to end and provided at the joints with what we willdesignate as iish-plates 5. By thus forming the track it can be readilymade in` the length designed. The track is suspended from the cable 9 bymeansY of brackets 0, placed at desired intervals apart, one end ofwhich brackets is clainped to the cable 2 and the lower end bolted orotherwise secured to the track 3, the brackets 6 being arched so as tolie to one side of the track and its support in order that noobstruction may be offered to the free travel of the lamp-carriage,which will move upon the track. The cuter end of the tra-ck 3 will beconnected to the cable 2 by means of an arni 7, which will be suitablyclamped to the cable. The track 3 extends inward to a point adjacent toone of the poles l, and at that point is curved, as illustrated, andthen extended downward parallel with the pole to a point at or adjacentto thebase of the pole, and is bra-ced and supported from the pole bythe brackets G, formed as before described, and one end of which will besecured in any suitable 1nan ner to the pole, while the other end willbe secured to the track, as previously described.

Upon the track will travel the lamp-carriage 8, which will be made inthe form of a frame of any suitable pattern and which will be providedwith the two sets of sheaves il, each set being secured to a plate l0,pivotally ccnnected to the frame, so as to oscillate, the sheaves ofeach set being arranged so that one will bear against the top of thetrack and the other against the under side of the track, thus preventingthe carriage from leaving the track.

at the curve.

The carriage is moved over the track by means of an endless wire orcable 1l, which is wound around a drum 12, located near the lower partof the pole 1,and connected to the i carriage say, at the point 13, sothat when the endless cable is drawn in one direction the carriage willbe moved along the track and brought to the lower part of the pole, sethat the carbons can be renewed, and when drawn in the other directionthe carriage will be moved along the track until it reaches thehorizontal portion thereof and then moved along that portion until itreaches the point where the lamp is to remain suspended. This endlesscable at the outer end of the track is passed around a sheave 1st,supported from the arm 7, and at the point where the curve or bend ismade in the track it passes over the two sheaves 15, supported by abracket 1G, which preferably is made of two arms, as shown, extendingfrom the upper part of the pole 1. The slack in the endless cable istaken up in the travel of the carriage by a sheave 17, supported fromthe carriage at its ripper end and over which sheave the endless cablewill be drawn. This sheave 17 will also act to lift the endless cablefrom the sheave 15 at the curve in the track, above which the sheave 17will pass as the carriage travels around the curve and after thecarriage has passed the curve the endless cable will drop back onto itssheave and thus be supported is made in the track both the track and thebracket 16 are braced by means of an arched bracket 18, one end of Whichis secured to the bracket 1G and the other to the track 3, this bracketbeing so formed that the carriage 'and sheave 17 will pass withoutobstruction.

The drum 12 is journaled in a suitable box 19, located at the lower partof the pole 1, and is provided at one end with a toothed wheel 20, abovewhich is a sliding pawl 2l, which has the iinger 22 projecting to apoint near to the shaft 23 of the drum, so that when the 'crank 24 isslipped onto the shaft 23 it will contact with the lower end of theiinger 22 and thus lift the pawl from engagement with the toothed wheel2O and hold it out of engagement w-hile the crank 24 is on the shaft 23and the drum is being turned in the operation of either raising orlowering the lamp by moving the carriage over the track. The box 19'willhave a door provided with a lock and key, so that the druni cannot betampered with.

The lamp 25, which may be of any approved pattern, will be pivoted tothe lower end of the carriage 8, and a shoulder or stop 26 will beformed on the lower part of the carriage at such point that when thecarriage passes from the horizontal to the upright portion of the trackand the lamp swings to its vertical position it will strike against thestop 2G and the stop prevent the lamp from coming in contact with thetrack.

At the point where thecurve The brackets 6 may be made in one piece, butif desired they can be made in two parts, one part being made to passthrough a socket 27, formed on the other part, and be held therein by aset-screw 28. In this way the brackets can be lengthened or shortened,so as to co1npensate for any sagging in the track and preserve the sainein a true horizontal or vertical position.

The numeral 29 designates a rod supported in a bracket 30 of thelamp-carriage and provided at opposite ends with the insulators 31,around which will pass the light-wires .52, which pass from the mainline to the lamp, which wires will lie on opposite sides of 'alie track.

The track made up of the sections can be formed of comparatively thinplates, so that the weight of the entire track will be comparativelyligh t, thereby `pcrmittin g the track to be connected to the cable 2before the latter is secured in position, the track being raised intoposition by lifting the cable 2 and then securing the cable first to onepole and then to the other. The upright portion of the track can besecured to the pole after the other part has been secured in place. Thetrack being made in sections it can easily be given additional length byadding one or more sections after reaching the place where it is to beerected and to suit the conditions as they may exist 'at the time. Theseveral parts being each simple in construction can be made at littlecost, thus rendering the en tire structure comparatively inexpensive andsuch as is practical where the cost of construction is an item to becarefully considered and which in many places would prevent theadvantages of a structure of this character being availed of.

\Ve have illustrated and described with. particularity the preferreddetails of construction of the several parts of the apparatus; butchanges can be made in such details and the essential features of ourinvention still be employed.
